Answer:
y = -2.5x + 4
Step-by-step explanation:
Slope intercept form: y = mx + b
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 5x from both sides.
5x (-5x) + 2y = 8 (-5x)
2y = 8 - 5x
Next, divide 2 from both sides to isolate the y.
(2y)/2 = (8 - 5x)/2
y = (-5/2)x + (8/2)
y = -2.5x + 4
y = -2.5x + 4 is your answer.

Answer:
The big polygon is double the size of the original, So the side question mark is 5 and the degrees is 1, 26.5 and 2, 41 degrees
Step-by-step explanation:
Prove:
Using mathemetical induction:
P(n) = 
for n=1
P(n) = 
= 6
It is divisible by 2 and 3
Now, for n=k, 
P(k) = 
Assuming P(k) is divisible by 2 and 3:
Now, for n=k+1:
P(k+1) = 
P(k+1) = 
P(k+1) = 
Since, we assumed that P(k) is divisible by 2 and 3, therefore, P(k+1) is also
divisible by 2 and 3.
Hence, by mathematical induction, P(n) = is divisible by 2 and 3 for all positive integer n.
It would be A 9 deposits of 40 dollars.
If you deposit forty dollars so positive nine times you aren’t going to want to write out 40+40+40….. when you can just say 9x40 once.
